This method involves attaching electrodes to the chest, arms, and legs to measure the electrical activity of the heart. ECG is considered the gold standard for measuring HRV.
This method involves using a device to measure the amount of light reflected off the skin to detect changes in blood flow.
This method involves using a device that measures acceleration to detect changes in heart rate.
Some heart rate monitors, such as those used in fitness tracking devices, can also be used to measure HRV.
There are several apps available that claim to measure HRV using the camera and microphone on a smartphone.
HRV can also be measured manually by taking the pulse and counting the number of heartbeats in a specific time period.
Some HRV measurement techniques involve performing breathing exercises to modulate the activity of the sympathetic and parasympathetic nervous system.
